When Christ was crucified on the cross, He not only provided the payment for sin, but by the stripes he bore, He provided for healing. Even though we believe in medical science and taking care of ourselves we also believe in divine healing. We call this divine intervention.
We have been redeemed from the curse so the blessing of Abraham could come upon us! In Hebrew man of sorrows is translated man of pains and grief is translated as sicknesses. So you could say that Jesus took the sicknesses and pains of the human race upon himself! Don't count yourself out! God doesn't discriminate! Healing is provided for you today!
